Title: Controlling a Sintering Process
IPC: C04B35/645
Filed: 1981-09-23
Abstract: A method of and apparatus for sintering a sinterable mass (M) of particles (1), metallic or nonmetallic, by applying thereto thermal energy and pressure simultaneously. A beam of acoustic waves is injected into the sinterable mass by an electromechanical transducer (13). The same transducer or another transducer (15) disposed in the propagation path of the acoustic waves senses a change in their level, that occurs as the particles (1) coalesce, to produce a control signal which is applied (via leads 17 b, c, d) to a power supply (11, S) and/or a compression system (2-10) to modify the thermal energy and/or pressure applied to the mass. Conductive particles are heated by passing current through them, in this case the current is kept constant by varying the force applied by a ram 5 in response to current measurement at 12, 12a. <IMAGE>

Abstract: A combination changing method is used in an access control system which includes one or more keys encoded at a central console with a function code, a key identification code, a modifier code and a key combination code and one or more locks having at least one memory level in which a lock identification code and a lock combination code are stored. A key is initially inserted into a selected lock and the data from the key transferred to the lock. The lock identification code is first compared with the key identification code. If there is no correspondence, power to the lock is turned off. If the identification codes correspond, the key combination code is compared with the lock combination code. If the combination codes correspond, the lock opens. If the identification codes correspond but the combination codes do not, the modifier code and the lock combination code are combined according to a predefined set of logical and/or arithmetic operations to generate a computed combination code which is compared with the key combination code. If the comparison is successful, the computed combination code is stored in the lock in place of the lock combination code and the lock opens <IMAGE>
